loadNFTMarker and loadNFTMarkers in ARControllerNFT.ts are not updated

[kalwalt]

I missed to change some part of the code done in #231.
loadNFTMarkers (ARControllerNFT.ts) should be:

(ids: number[]) => {
  this.nftMarkerCount += ids.length;
  onSuccess(ids);
},

but now is

(ids) => {
    this.nftMarkerCount += ids.length;
    onSuccess(ids);
},

loadNFTMarker should be:

 (ids: number) => {
    this.nftMarkerCount += ids.length;
    onSuccess(ids);
},

(ids: any) => {
     this.nftMarkerCount += ids.length;
     onSuccess(ids);
},
